Recursively update all (with `git pull`) sub-directories (upstreams) in a parent directory (assuming many sub-directories).

update-script.sh

#!/bin/bash

for dir in *; do

        if [ -d "$dir" ]; then
        
                echo -e "\nUpdating $dir extension, please wait...\n";

                (cd "$dir" && git pull origin master)

                echo -e "\n$dir extension updated..."
        fi
done

echo -e "\n\nWell done, all directories updated :)"d
